Technical field

The invention belongs to inertial navigation fields, are related to a kind of vehicle-mounted inertial guidance data acquisition system.

Background technique

Inertial navigation is a kind of missile-borne core component, for measuring the information such as the current position of guided missile, posture, speed, Precision represents the performance of inertial navigation.A set of inertial navigation generally requires another set of high-precision when carrying out dynamic property verification test Inertial navigation provides the benchmark of navigation information, to compare, the former is known as sub- inertial navigation, and the latter is known as main inertial navigation.Carry out dynamic When being able to verify that test, main inertial navigation and sub- inertial navigation can be mounted in a dedicated automobile, the two connects firmly flat in the same benchmark On face, acquires the navigation information of the two respectively with computer, data are compared and analyzed again after the test.

The data of two inertial navigations are acquired respectively by computer in track test at present, and deficiency is: collected data are Two unique files, it is necessary to it just can be carried out off-line analysis after the end of the test, it can not real time contrast；Two groups of data can not be accurate right Neat time shaft；Off line data analysis is time-consuming more.

Summary of the invention

Present invention solves the technical problem that: for the deficiency of existing Test Data Collecting method, proposing one kind can be simultaneously Acquire the vehicle-mounted inertial guidance data acquisition system of two paths of data and real-time processing data.

Technical solution of the present invention:

The present invention provides a kind of vehicle-mounted inertial guidance data acquisition system, comprising: data collector 1, main inertial navigation 2,3 and of sub- inertial navigation Show computer 4,

Main inertial navigation 2 and sub- inertial navigation 3 transfer data to data collector 1 simultaneously, and data collector 1 parses two-way respectively Data, time alignment axis, in real time calculate data, obtain the navigation error information of sub- inertial navigation 3 with main inertial navigation 2, then by institute There are data to export to display computer 4.

In addition, including processor, memory, data processing software and data board inside data collector 1；

Wherein, pass through processor time alignment axis after receiving the data of main inertial navigation 2 and sub- inertial navigation 3, pass through data processing Software parses initial data, realizes Data Matching, and accordingly calculated data as needed, all data are stored in storage Device.

In addition, power supply 5 is the power supply of data collector 1 the system also includes power supply 5.

In addition, main inertial navigation 2 and sub- inertial navigation 3 are counted with data collector 1 by RS422 or RS232 data/address bus respectively According to transmission.

In addition, data collector 1 is carried out data transmission with display computer 4 by RS232 data/address bus.

In addition, data collector 1 has data storage function, data are exported by USB interface or network interface.

It is connect in addition, data collector 1 passes through RS232/RS422 interface 8 all the way with main inertial navigation 2, all the way RS232/RS422 Interface 9 is connect with sub- inertial navigation 3, receives the data of main and sub inertial navigation respectively.

In addition, data collector 1 is connect by RS232 interface 10 all the way with display computer 4 again.

Beneficial effects of the present invention: being built into a kind of vehicle-mounted inertial guidance data acquisition system by the way that data collector is added, This system architecture mode flexibility and changeability, widely applicable, a data collector can dock the main and sub inertial navigation of different model, can be real Now to the real-time processing of main and sub inertial guidance data, and data collector has data storage function, small in size, light-weight, convenient for taking Band.In addition, data collection system is easy to operate, data processing method is simplified, testing crew can be allowed to find that data are different in time Often, decision ahead of time improves test efficiency.

Detailed description of the invention

Fig. 1 is the architecture diagram of vehicle-mounted inertial guidance data acquisition system of the invention.

Specific embodiment

Invention is further described in detail below.Fig. 1 shows the framves of vehicle-mounted inertial guidance data acquisition system of the invention Structure.As shown in Figure 1, vehicle-mounted inertial guidance data acquisition system of the invention includes data collector 1, main inertial navigation 2, sub- inertial navigation 3, display Computer 4, power supply 5.Wherein data collector 1 is connect by RS232/RS422 interface 8 all the way with main inertial navigation 2, all the way RS232/ RS422 interface 9 is connect with sub- inertial navigation 3, receives the data of main and sub inertial navigation respectively.Data collector 1 is connect by RS232 all the way again Mouth 10 is connect with display computer 4, for sending processed data.Data collector 1 is powered by power supply 5, and possesses one USB interface 6 and a network interface 7, for exporting the data of storage.

Include processor, memory, data processing software inside data collector 1, receives main inertial navigation 2 and sub- inertial navigation 3 Data after by processor time alignment axis, initial data is parsed by data processing software, realizes Data Matching, and according to It needs accordingly to calculate data, all data are stored in memory.Initial data and the place of main inertial navigation 2 and sub- inertial navigation 3 The data managed are exported by RS232 interface 10 to display computer 4, convenient for test people after being reintegrated by data processing software Member's real-time monitoring.Data can be stored in data collector 1 initial data with treated, after the end of the test insert u disk Enter USB interface 6, automatically u disk is written in all data by data collector 1.Data collector 1 can also be connect by cable by network Mouth 7 is connected to a computer, realizes the operations such as data export and deletion.

The way of inertial navigation dynamic property verification test is carried out using the vehicle-mounted inertial guidance data acquisition system are as follows: acquire data Device 1 is connected to the main inertial navigation 2 of benchmark by RS232/RS422 interface 8, tested by the connection of RS232/RS422 interface 9 Sub- inertial navigation 3 connects display computer 4 by RS232 interface 10, and powers on 5.When starting test, main inertial navigation 2 and sub- inertial navigation 3 power on respectively, respectively output data to data collector 1, and data collector 1 receives the matching for carrying out data after data automatically And calculating, while data are exported to display computer 4 by treated.After the test, main inertial navigation 2 and the lower electricity of sub- inertial navigation 3. It when needing to export data, is powered using power supply to data collector 1, u disk insertion USB interface 6 is derived automatically from data, it can also Network interface 7 is connected by cable with a computer, the behaviour such as is exported and deleted to the data stored in data collector 1 Make.
